BACKGROUND

1. Field of the Invention

The present invention relates to an integrated waste catalyst cleaningapparatus for residual hydro desulfurization (RHDS) and vacuum residuedesulfurization (VRDS) processes and a method thereof, and moreparticularly, to an integrated waste catalyst cleaning apparatus forresidual hydro desulfurization (RHDS) and vacuum residue desulfurization(VRDS) processes and a method thereof in that a desulfurization wastecatalyst produced in the residual hydro desulfurization (RHDS) andvacuum residue desulfurization (VRDS) processes can be organicsolvent-cleaned and organic acid-cleaned in one reactor.

2. Description of the Related Art

According to the notice on the use of clean fuels, the sulfur contentcontained in the heavy oil has been gradually decreasing. In addition,the use area of the low-sulfur heavy fuel oil has been graduallyexpanded. Since the heavy oil such as a bunker C oil has a high sulfurcontent, the consumption thereof is rapidly reduced, while theconsumption of light oil products has increased significantly.

Most domestic refineries have introduced heavy oil cracking anddesulfurization facilities so as to cope with the light oil trend of theoil supply and demand structure and the low-sulfurization trend of theoil products. The main process for upgrading of the Heavy oil includesan Atmospheric Residue Hydro DeSulfurization (AR-HDS), a Vacuum ResidueHydro DeSulfurization (VR-HDS), a Residue Fluid Catalytic Cracking(R-FCC), and a VGO hydrotreating process (VGO-HC) and the like. Here, itshould remove large amounts of sulfur and heavy metals contained in theheavy oil for a smooth operation of the process.

The hydrodesulfurization catalyst used commercially herein is aNi—Mo/Al₂O₃, a Co—Mo/Al₂O₃ and the like. At this time, the catalyst ispoisoned owing to the deposition of the sulfur and the heavy metal etc.and the life thereof come to an end. Generally, the waste catalyst isreplaced with a new catalyst in one cycle or two cycle each year. Thewaste catalyst amount is approximately 23,000 tons per year and the newcatalysts rely on imports from abroad.

In the meantime, since the catalyst self-components metals (Ni, Mo, Co,W) in addition to V, Ni and Fe and the like contained in the oil aredeposited on the produced waste catalyst, it contains a considerableamount of valuable metals. The part thereof is treated through a waterleaching after a soda foasting, which is most widely used method, bymeans of the recovery enterprise. However, there are problems in that alot of energies is consumed owing to the hot-melt (600 to 1000° C.) andthe rear end is blocked owing to the discharge of dust etc. according tothe wear between the waste catalysts. Also, in case of the collectionaccording to the water leaching, the vanadium, which is the largestcontent in the valuable metals, is collected and then, the molybdenumand the nickel are collected to be discarded. However, there is aproblem of environmental pollution during the waste landfill owing to aburden of the disposal costs and the difficulty of a complete recoverythereof. In addition, a part of the waste catalysts is roasted and then,it exports to China etc. Accordingly, the valuable metals such as thevanadium and the molybdenum and so on, which are natural resources, havegone abroad.

The domestic refinery hydro desulfurization (HDS) process is run for along time. However, it takes an interest in only the collection of thevaluable metals, while it does not care about the process of clearingthe waste catalysts. Accordingly, the domestic technical standard isbelow the restoration level of the waste catalysts from the keytechnologies to the engineering technologies.

Korea Patent Publication No. 10-2013-0026431 (publication date: Mar. 3,2013) relates to a method for recovering catalytic metals from theresidue of the refined oil and is characterized in that the residue ofthe refined heavy oil is pyrolyzed and combusted in a high temperatureof 900° C. for the production of the ash. However, where the residue ispyrolyzed in a high temperature through the above technique, since agamma-alumina material used as the carrier of the catalyst is changed toa beta-alumina phase and a sintering phenomenon etc. is generated in thetransition metal materials such as a Ni—Mo or a Co—Mo etc., there is alimit in that only the valuable metals are collected without the reusingit.

Also, Korea Patent registration No. 10-1434437 (Registration Date: Aug.20, 2014) filed and registered by the present applicant relates to areproduction system of the desulfurization waste catalyst in residualhydro-desulfurization (RHDS) and vacuum residue hydro-desulfurization(VRHDS) processes. In the waste catalyst recovery system implemented bythe above technology, since each step processed in a cleaning tank, adrying tank, and a collecting tank is conducted in the differentdevices, there are problems in that the installation expenses isincreased and the working is inconvenient.
